I have noticed a bit of hesitation and a bit of shaking lately. A check engine light came on and went back off with no code stored in the computer. I noticed a very very strong fuel smell when driving today so i lifted the hood when i got home and it was still there. I crawled under the Nav and an exhaust clamp was wet. I wiped it with my finger and it was unburned fuel. Well, I had the Nav lifted in the front, which had fuel leaking out of the muffler. Any ideas?
